Bare-Metal Hypervisor Deployment via Dynamic Device Remapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying and booting cloud hypervisors is inefficient due to lack of dynamic remapping and reconfiguration capabilities, leading to slow deployment times and suboptimal platform utilization in multi-tenanted environments.
Innovation Solution
The introduction of a bare-metal operating system called PODS, which enables dynamic remapping of device-specific workloads and reconfiguration of platform attributes without requiring a system reboot, allowing for faster boot times and efficient execution of heterogeneous workloads across different hypervisors and hardware architectures.

1Productivity
If a traditional bare-metal hypervisor deployment is used, then system stability is maintained, but deployment time is slow and platform utilization is suboptimal
Solution Approach 1:
The patent implements preliminary action by pre-configuring virtual objects and device paths before hypervisor deployment. The bare-metal operating system prepares virtual device objects and mappings in advance, allowing the hypervisor to be deployed and booted rapidly without requiring time-consuming configuration steps during the deployment process itself.
Solution Approach 2:
The patent applies dynamics by enabling dynamic remapping of device-specific workloads and reconfiguration of platform attributes at runtime. The system can dynamically adjust device paths and virtual object mappings without requiring system reboots, allowing flexible adaptation to different hardware configurations and workloads while maintaining fast deployment times.
2Adaptability or versatility
If device-specific workloads are statically mapped, then hardware compatibility is ensured, but adaptability to heterogeneous workloads is limited
Solution Approach 1:
The patent uses an intermediary approach by introducing virtual device objects as mediators between physical hardware and virtual workloads. These virtual objects serve as a translation layer that maps physical device paths to virtual representations, enabling workload portability across different hardware platforms while abstracting the complexity of direct hardware mappings from the user and system.
Solution Approach 2:
The patent implements universality by creating a unified virtual object framework that can represent different types of hardware devices and workloads in a consistent manner. The same virtual object mechanisms work across heterogeneous hardware architectures and workload types, providing universal adaptability without requiring separate mapping mechanisms for each device type.
3Ease of operation
If system reboot is required for reconfiguration, then system stability is maintained, but operational flexibility is reduced
Solution Approach 1:
The patent enables dynamic reconfiguration by allowing the bare-metal operating system to remap device paths and reconfigure platform attributes at runtime without requiring system reboots. The system can dynamically adjust virtual object mappings and device assignments while maintaining operational stability, combining the flexibility of reconfiguration with the reliability of continuous operation.

AI summary
An information handling system may include at least one processor and a storage resource having a bare-metal operating system thereon. Upon a first boot of the information handling system, the bare-metal operating system may deploy a hypervisor to be executed by the at least one processor; and implement a device enumeration protocol mapping virtual objects associated with the bare-metal operating system to virtual device objects associated with the hypervisor.
